48 MADRAS FISHERIES BULLETIN VOL. XIV, 



Skagen, the same. 



Gothenburg. 40 tons per day of frozen fish and cold storage for 1.200 

 tons. 



North Cape, a daily freezing power of 20 tons and storage capacity for 

 400 tons. 



Abe, the same as the North Cape installation. 

 The builHing at Esbjerg, which I had the privilege of inspecting 

 with work in full swing, was specially designed, and appears admir- 

 able for its purpose. It consists of two floors ; both appropriated in 

 major part to the purpose of cold storage rooms. 



The receiving room on the ground fioor is furnished with deep 

 washing tanks formed of concrete. Into these the contents of the 

 fish boxes are emptied and rinsed in fresh water as quickly as pos- 

 sible to clean them from slime and dirt. Some fish as herring and 

 mackerel do not stand even a short immersion in freshwater with- 

 out deterioration, hence the need for celerity. The haddock on the 

 other hand is tolerant and so constitutes one of the best fishes for 

 freezing. Salt water is of course preferable but at Esbjerg the har- 

 bour water is too foul for the purpose ! 



As soon then as possible the washed fish are removed by means 

 of hand nets and thrown on trestle tables alongside to be sorted out 

 according to size, and placed, size by size, in different shallow 

 wire-net baskets. It is necessary to do this for the size of the fish 

 naturally controls the time required to freeze them, other conditions 

 being similar (sardines take 15 minutes to freeze while salmon of 

 good size require over two hours). The baskets are made with 

 perforated zinc sides, and bottoms of square mesh galvanized iron 

 wire-netting. Length 90 cm. by 50 cm. with a depth of 35 cm. 

 These as filled are stacked in piles 7 baskets high, all containing 

 the same grade of fish and secured by a special clamping frame. 

 When complete each pile is considered a unit ami is sent upstairs 

 by a small electric lift to the freezing room. 



The freezing room is on the first floor with the tanks sunk in 

 the floor. Of these there are three series. At one side is a long 

 row of small deep tanks or rather pits {18 at Esbjerg\ each capable 

 of taking a freezing unit of seven baskets. Parallel with these is 

 a second series of three long tanks occupying the centre of the floor 

 and outside of this is a third row of six other tanks. The latter 

 tanks are where the brine is cooled to the necessary degree ( — 14^° 

 C), the interior being filled with coils of pipes containing CO2.
